Studies on Interaction of Essential Metal Ions with Bioactive Ligands

摘要

Complexation reactions of nitrilotriacetate (NTA) and penicillamine with Cu~(2+) and Co~(2+) have been studied in solution phase using paper electrophoresis technique.The stability constants of the complexes Cu(II)-nitrilotriacetate-penicillamine and Co(II)-nitrilotriacetate-penicillamine have been found to be 6.64 +- 0.03 and 5.86 +- 0.05 (logarithm stability constant values),respectively at 35 deg C and ionic strength 0.1 M.
